I posted on the "other" forum, but can use all the input I can get!

2011 limited 103, have 255 cams, need slipons with with a small noise increase (wife!). TTS tuner and AC. The slip ons are the big question, as I want only a modest increase in decibals. I would appreciate some recommendations.
How much torque do you figure this combo will provide? Do I need to cut open the cat chamber and gut it?

 

Did the 255 cams come stock or did you add them?? trying to find out the stock cams that come with the 103 engine??

I read they come with the same cams as the 96. I haven't installed the 255 cams yet, I only have 900 miles on the bike.
